Create Smart Copy of the guest attached volume mounted to /mnt/myexportĪsmcli create smart-copy –-source /mnt/myexport.VERIFICATION: Confirm group access is set the way you want it.

Create PS group access (one time configuration step)Īsmcli create group-access –-name MYEQLGRP –-ip-address 10.10.10.100 –-user-name asmleadmin.The example below uses an account named “asmleadmin”

Each system that has ASM/LE installed needs an account to interact with the volumes, and this offers the least privilege necessary to interact with the Smart Copies. I’m not going to dive into each option, but rather, provide a simple example of how one can create a smart copy, and mount it if needed.īefore you get started, you may wish to choose or create a dedicated account on your PS Group that has volume administrator privileges. The asmcli help command will provide you with a complete listing of options. At the root of the new found intelligence is the “ asmcli” command. The new version offers a complete command set that fills the void. Since the snapshots generate their own unique IQN, one needed a way to query for, and pass these variables as parameters. However, when it came to manipulating that snapshot from a guest, such as turning it online, or connecting to it, there was no way to do so. One could create volume snapshots from the Group Manager GUI, and even schedule them. The old version of HIT/LE didn’t offer any way of creating a snapshot inside the guest.

Add access to a PS Series Group called "MYEQLGRP”.

Compare this to the instructions I provided on my post about HIT/LE 1.0, and you’ll see quite a difference. Below demonstrates a simplified method of connecting an existing volume to a VM running the new HIT/LE 1.1. The configuration and connection of volumes seems to be greatly simplified. No amount of glue or duct tape helped in bridging the functions needed with snapshot manipulation inside the guests. The biggest challenge I had was finding an automated way to take snapshots of these Linux guest attached volumes, and mount them to a Linux media server so that the data could be archived onto tape. The problem was that it left out key abilities that prevented an automated way to manage those snapshots for specific purposes. Version 1.0 did a good job applying the benefits of guest volumes to Linux based Operating Systems. This wasn’t listed in the release notes, but was immediately a noticeable improvement.

A new installer and configuration process.

A new feature that will allow you to create, manage, and schedule volume snapshots (Smart Copies), clones, and replicas from inside of the guest.

According to the documentation, RHEL 5.5 is no longer supported, which is a change from the previous edition. Versions 5.7 through 6.2 of CentOS are now supported. CentOS, the binary compatible/clone to RHEL is now supported. Version 1.1 was released in April of 2012, and it addressed some of the observations I had about HIT/LE 1.0. While it has been running well in our environment, it was definitely a 1.0 product when it came to features and configuration, so I was anxious to see what was in store for the next version. At the time, the HIT/LE was beginning to play an important role in how we housed large volumes of data, and I wanted to share with others what I learned in the process. It was just last September that I wrote about Using the Dell EqualLogic HIT for Linux (HIT/LE) Version 1.0.
